Summary: This study assessed the future glacial lake outburst flood (GLOF) hazard of the South Lhonak Lake in the Sikkim Himalaya, considering the potential impacts of continued glacier retreat and avalanche events. The results indicate that the lake's growth may lead to overtopping of the frontal moraine, triggering GLOFs and causing significant downstream impacts.

Summary: This study used a glacier ice thickness distribution dataset to identify potential glacial lakes in the Tibetan Plateau and its surroundings. The study found a significant number of potential glacial lakes and provided morphological metrics to determine their formation probability. The results also highlighted the concentration of these lakes in the lower half of individual glaciers and within a specific elevation range. The findings contribute to our understanding of future glacial lake formation and distribution in the region and have important implications for flood prevention and water security measures.

Summary: As reports on glacial lake outburst floods (GLOFs) have increased with global warming, it is critical to have a robust GLOF susceptibility assessment approach for disaster prevention. This study used the Analytic Hierarchy Process (AHP) and various data sources to assess the potential hazard grades of glacial lakes in the Nidu Zangbo Basin in the Tibetan Plateau. The approach successfully identified high potentially hazardous glacial lakes and proved its effectiveness by accurately predicting a GLOF event in 2020.

Summary: The Sikkim Himalayan glaciers and glacial lakes are experiencing the impact of climate change, leading to an increase in the total lake area, particularly in the Gurudongmar lake complex. Climate change and ongoing glacier retreat are the main factors contributing to the expansion of the lake areas, with changes in precipitation levels affecting the expansion velocity of the glacial lakes.

Summary: Glacial lake outburst floods (GLOFs) pose a serious threat to Himalayan communities, but mitigation strategies are limited and future hazards are rarely considered. This study assesses the current and future GLOF hazard for Gepang Gath Lake in the Western Himalayas, considering rock and ice avalanches cascading into the lake from areas of degrading permafrost. The study evaluates different scenarios of GLOF impacts, erosion patterns, and debris flow hydraulics, taking into account the engineered lowering of the lake. The findings demonstrate that the size of the future lake does not determine the size of GLOF events in Sissu, highlighting the importance of avalanche location and impact. Lowering the lake by 10 or 30 meters can reduce the high-intensity flood zone, but the Sissu helipad remains at risk under moderate-to-large scenarios. This study provides insights into the effectiveness of lake lowering as a GLOF mitigation strategy.

Summary: This study investigates ice dammed glacial lake outburst floods (GLOFs) associated with surge glaciers, focusing on the Khurdopin Glacier in the Karakoram region. The research analyzes seven surge periodical cycles and three surge events using satellite imagery, identifying the importance of surge velocities in controlling conduit development and subsequent GLOFs. A subglacial drainage model was developed to estimate peak discharge timing in GLOF hydrographs, highlighting the dominance of conduit melt enlargement as a drainage process. The study's results suggest that the proposed model could be widely applied for surge-type glaciers worldwide to anticipate ice-dammed lake formation and GLOFs, allowing for timely precautionary measures and reducing downstream damage.

Summary: Glacial lakes in the Himalayas have been the source of over 100 glacial lake outburst floods (GLOFs) since 1900, causing significant casualties and economic losses. This study presents a thorough inventory of potentially dangerous glacial lakes (PDGLs) and improves the evaluation system to identify high-hazard glacial lakes based on key assessment factors. The best combination of assessment factors is applied to 1650 glacial lakes in the Himalayas, identifying 207 as very high-hazard and 345 as high-hazard, which can serve as benchmark data for assessing GLOF risks for local communities.

Summary: Thousands of glacier lakes have formed in high mountains since the early 20th century following glacier retreat. Some of these lakes have released large amounts of water and sediment with disastrous consequences downstream. However, it is unclear whether the reported rise in glacier lake outburst floods (GLOFs) is due to a warming atmosphere or simply increased research efforts. This study finds that the number of reported GLOFs has decreased since the 1970s, coinciding with changes in annual air temperatures and number of field-based glacier surveys. The findings suggest a weak coupling between temperature-driven glacier processes and GLOF occurrences, or the possibility of overlooked outbursts.

Summary: Glacial lake outburst floods (GLOFs) are considered one of the most serious hazards in deglaciating high mountain regions worldwide, highlighting the need for GLOF hazard and risk assessment. Recent studies have attempted to assess GLOF hazard on a regional and national scale, but simplification may lead to neglect of qualitative characteristics. This study explores using quantitative characteristics and ratios to approximate lake dam types, but results show negligible differences in relative frequencies along the spectra.

Summary: This study examines the longevity of geomorphic diagnostic features of glacial lake outburst floods (GLOFs) and its implications for building GLOF inventories. The analysis of 160 GLOFs in the Tropical Andes reveals that breached dams and pre-GLOF water levels can persist for over 102 years, while outwash fans and impact areas are more prone to degradation and vanishing. This highlights the importance of considering the persistence and degradation of GLOF diagnostic features in inventory building.

Summary: The present study aims to delineate groundwater zones in the Bist-Doab region of Punjab, India using multi-criteria decision analysis based on land-use/cover pattern, groundwater table, and groundwater quality for domestic and agricultural use. The study reveals that about 71% of the region is used for agriculture, 12% for built-up areas, 7% for forest cover, 5% for tree plantation, 3% for water bodies, and the remaining 2% for open areas. Additionally, the groundwater table shows that around 8% of the region has a groundwater table below 30 m, mainly concentrated around urban areas. Qualitatively, the study finds that certain areas have unsuitable groundwater for domestic consumption and irrigation, with poor water quality mainly observed in urban agglomerations due to high urbanization and industrialization.

Summary: Small glaciers in temperate mountain regions have experienced significant reduction and unprecedented melt rates in recent years. Some glaciers have transitioned from clean ice to debris-covered or even rock glaciers. This study examines the surface elevation change of the Popera Alto glacier in the Sesto Dolomites using LiDAR and Structure from Motion surveys, and analyzes its evolution in terms of surface cover and geomorphic processes. The glacier has lost an average of 0.35 m water equivalent per year over the past 16 years, with active modification of its surface cover by geomorphic processes. The role of debris and local topography feedback has allowed the resilience of the glacier, leading to a marked difference between the current environmental equilibrium line altitude (envELA) and the effective ELA (effELA) of the glacier.

Summary: The study investigates the relationship between glacial dynamics and lake sedimentation during the mid-Holocene climate variability in the Southern Zanskar ranges. It utilizes geomorphological disposition, elemental geochemistry, and optical chronology of relict lake sediment to reconstruct the pattern of minor glacier responses to climate variability. The results indicate six centennial to millennial-scale climatic phases, with warmer phases represented by decreased mineralogical fine grain flux and increased coarse grain flux. The study highlights the potential of relict lake sediment and para/peri-glacial landforms in understanding glacial dynamics and climate change during the Holocene.
